On the Power Flows Page, the icon will flash when there is a
warning. Listed below are the warning codes and their solutions.
Operation and Display Panel
25 RCMU test fault None 1. Turn the inverter off and then back on using the main switch.
2. If the error remains, contact your installer.
26 Model setting fault None 1. Turn the inverter off and then back on using the main switch.
2. If the error remains, contact your installer.
27 Battery Voltage Drop None 1. Battery voltage drop below 30V.
2. Check the battery BMS errors and the wiring.
3. Turn the inverter off and then back on using the main switch.

Stacking Canbus communication error
1. Turn the inverter off using the main switch and check the canbus communication cables.
2. Turn the inverter on. If error remains, contact your installer.
54 Power island
1. Turn the inverter off and then back on using the main switch.
2. The inverter will wait for 5 minutes before attempting to connect to the Grid.
3. If the error remains, contact your installer.
55 Grid is disconnected
56 Grid voltage exceeds the upper threshold
57 Grid voltage falls below the lower threshold
58 Grid frequency exceeds the upper threshold
59 Grid frequency falls below the lower threshold
61 Battery voltage is too low
1. The battery voltage is less than 44V (lead-acid) or the SOC is lower than 10% (Lithium).
Battery backup function will be turned off and the system output can only work with the
Grid.
2. Wait for the PV or Grid to charge up the battery. The error code will change to 62 once the
battery voltage is above 44V or the SOC is above 10%.
62 Low battery SOC level
1. The battery voltage is less than 47.1V (lead-acid) or the SOC is less than 40% (Lithium).
2. Wait for the PV or Grid to charge up the battery. The error code will clear and battery
backup function will be enabled once the SOC is above 60%.
63 Battery is not detected
1. Turn the inverter off using the main switch.
2. Check battery connection for any loose wiring.
3. Turn the inverter on. If error message remains, contact your installer.
64 Inverter output OCP
1.
Inverter output current exceeds the upper threshold.
2. Turn the inverter off and then back on using the main switch.
3. If error remains, contact your installer.
Alarm – On: 1s, Off: 1s
65 RS485 communication error
1. Turn the inverter off using the main switch and check all communication wires.
2. Turn the inverter on. If error remains, contact your installer.
66 Output derated
1.
When system temperature is too high, the output power has been derated.
2. Lower the load or lower the environmental temperature.
Notes:
System output lowered to 80% when the system temperature is higher than 80°C.
System output lowered to 60% when the system temperature is higher than 85°C.
System output restored to 100% when the system temperature is lower than 70°C.
25 RCMU test fault None 1. Turn the inverter off and then back on using the main switch.
